[0025] The principles and spirit of the invention will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are provided merely to enable those skilled in the art to better understand and implement the invention, and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided to make the invention more thorough and complete, and to fully convey the scope of the invention to those skilled in the art.

[0026] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Firstly, the application scenario of the interface performance test method of the embodiment of the application is described. The test machine, test equipment and machine to be tested in the application can be connected in the same preset line through a network. Specifically, a network interface can be set on the test machine and test equipment to realize network connection. The machine to be tested can set a network interface or directly connect to the network through wireless. Correspondingly, the test machine, test equipment and machine to be tested can communicate with each other through TCP / IP protocol and MQTT protocol after being connected in the same preset line. It should be noted that the method of enabling the test machine, test equipment and machine to be tested to communicate with each other through TCP / IP protocol and MQTT protocol is not limited. Here, only an example is given. As long as the method can enable the test machine, test equipment and machine to be tested to communicate with each other through TCP / IP protocol and MQTT protocol, it belongs to the protection scope of the application.

[0028] Further, the test machine in the application is a test terminal. After successful connection, the test machine can design Case (test case) according to the interface type and test performance type required by the machine to be tested. For example, when the interface type to be tested by the machine to be tested is a USB interface or a TYPE-C interface, the test performance type can include access performance and removal performance. Correspondingly, the Case can include the following instructions: connecting the USB / TYPE-C interface, testing the access performance of the USB / TYPE-C interface, removing the USB / TYPE-C interface and testing the removal performance of the USB / TYPE-C interface, etc. When the interface type to be tested by the machine to be tested is a DP interface or an HDMI interface, the test performance type can include testing the performance of the interface under different resolutions. Correspondingly, the Case also includes the following instructions: connecting the DP / HDMI interface, testing the interface performance of the DP interface and HDMI interface under different resolutions, etc. It should be noted that the application supports testing of multiple interface types. However, the application can design the Case according to the type of the interface to be tested by the machine to be tested, so as to issue the corresponding designed Case to test the interface to be tested by the machine to be tested. Here, when the machine to be tested needs to be tested, the order of testing is not limited.

[0029] Further, after the machine to be tested and the test machine (such as a terminal device) are connected to the same preset channel through a network, the test machine can issue a pre-set instruction to download the test tool, so that the machine to be tested (such as a computer) can download and install the test tool required for this test, such as a USB detection tool, a TYPE-C detection tool, a resolution switching tool, etc. according to the instruction. Moreover, the instruction to download the test tool can also be placed in the first step of the Case. After the Case is issued, the machine to be tested will first download and install the test tool required for use according to the instruction for subsequent use.

[0030] It should be noted that the application scenarios of the interface performance test method of the embodiments of the application described above are exemplary descriptions given for more clearly describing the schemes, and in actual application processes, the interface performance test method of the embodiments of the application can also be applied to other applicable scenarios, and the application does not make specific limitations on this.

[0031] Figure 1 The implementation flowchart of the interface performance test method of the embodiments of the application is shown Figure 1 .

[0032] Referring to Figure 2 The interface performance test method provided in the embodiment is applied to a test machine, and the method comprises the following steps: in step 101, a connection instruction is sent to a test device and a machine to be tested, the connection instruction carrying an interface identifier of a set interface to be tested this time, so that the test device accesses the set interface of the machine to be tested according to the interface identifier; in step 102, an interface test instruction is sent to the test device in the case where an access success signal sent by the test device is received; and in step 103, a test result of interface test of the set interface of the machine to be tested by the test device in response to the test instruction according to the interface identifier is received.

[0033] Specifically, first, the interfaces to be tested of the machine to be tested are connected with the corresponding access ports of the test device, and then the test device and the machine to be tested first perform self-checking and send the self-checking results to the test machine through TCP / IP protocol and MQTT protocol. In the process of testing the interface performance of the machine to be tested, the test machine always monitors the states of the test device and the machine to be tested through the network, so that the internal hardware of the test device and the machine to be tested and the network state are good, and the corresponding operations can be completed.

[0034] In operation 101, the test machine can send a connection instruction to the test device and the machine to be tested through TCP / IP protocol and MQTT protocol. The test device can determine the set interface of the machine to be tested that needs to be connected for testing according to the interface identifier of the set interface to be tested this time carried in the connection instruction, and connect the test connection end of the test device with the set interface of the machine to be tested. Here, the interface identifier shows the set interface of the machine to be tested that needs to be tested this time, such as USB1.0, USB2.0, TYPE-C1.0, HDMI interface or DP interface, etc.

[0035] The test connection end of the test device refers to a connection line in the test device that is pre-configured for testing the setting interface of the device under test, and is configured with interfaces of multiple types that match the setting interface of the device under test, for example, can include a USB interface, a TYPE-C interface, an HDMI interface, a DP interface, and the like. The interface identifier of the interface test carried by the connection instruction can include the device identifier of the device under test and the interface type and interface number of the setting interface to be tested.

[0036] In operations 102-103, after the test device connects the test connection end to the setting interface of the device under test according to the connection instruction, the test device can send a connection success signal to the test machine, and correspondingly, the test machine can receive the connection success signal sent by the test device through the TCP / IP protocol and the MQTT protocol. After the test machine receives the connection success signal, the test machine can issue a test instruction through the TCP / IP protocol and the MQTT protocol, so that the test device detects the corresponding setting interface of the device under test according to the test instruction, and receives the test result of the test device after detecting the setting interface.

[0037] In this embodiment of the application, in the case where the interface identifier indicates that the interface type of the setting interface of the device under test for this test is a DP interface or an HDMI interface, the test machine can receive the test result obtained by the device under test by responding to the test instruction to send a resolution identifier and a test signal corresponding to the resolution identifier to the test device, receiving the comparison result obtained by the test device by comparing the test signal with the corresponding original signal according to the resolution identifier, and sending the multiple comparison results obtained by the test device for the multiple resolutions supported by the device under test and the resolution identifier corresponding to each comparison result to the test machine as the test result.

[0038] Specifically, the device under test can support transmission and processing operations of audio and video signals of multiple resolutions, and when testing the DP interface and the HDMI interface, the interface performance of different resolutions supported by the device under test needs to be detected. Correspondingly, the device under test can send a resolution identifier and a test signal corresponding to the resolution identifier to the test device, and after the test device compares the test signal under each resolution with the original signal in sequence, receives the multiple comparison results corresponding to different resolutions sent by the test device. Further, the device under test can send the resolution parameter identifier for identifying the resolution and the comparison result corresponding to each resolution parameter identifier as the test result of the interface for this test to the test machine. In this way, for the device under test supporting multiple resolutions, the application can automatically test the performance of the interface of the device under test under multiple resolutions.

[0039] Further, the comparison of the test signal and the corresponding original signal to obtain a comparison result includes: comparing the test signal and the corresponding original signal to obtain a comparison result, and comparing the comparison result with preset parameter standard information; if the comparison result is within an error allowable range, the comparison result is displayed as good interface performance; if the comparison result is not within the error allowable range, the error is too large, and the comparison result is displayed as interface performance error. The comparison result can include the comparison results of the bit number, refresh rate, resolution and other parameters of the color digital signal.

[0040] In this embodiment of the application, in a case where the interface identifier indicates that the interface type of the set interface is a USB interface or a TYPE-C interface, the interface test instruction includes an interface access detection instruction and an interface removal detection instruction; correspondingly, the test result of the test device for testing the set interface of the machine under test according to the interface identifier in response to the test instruction includes: the test result obtained by the machine under test in response to the interface access detection instruction, the test result including: detecting whether the set interface is successfully accessed, obtaining an access detection result, and sending the access detection result to the test machine; in a case where the test device removes the set interface, detecting whether the set interface of the machine under test is successfully removed in response to the interface removal detection instruction, obtaining an interface removal detection result; and sending the interface removal detection result to the test machine; wherein the interface removal detection instruction is an instruction sent by the test machine to the machine under test in a case where the test machine receives the access detection result and the access detection result indicates that the set interface is successfully accessed.

[0041] Specifically, the machine under test can include multiple USB or TYPE-C interfaces, and thus all USB or TYPE-C interfaces of the machine under test need to be tested. Therefore, after the test device connects and turns on the access port corresponding to the USB interface or TYPE interface to be tested according to the connection instruction and the interface identifier carried by the connection instruction, the machine under test can receive, through the TCP / IP protocol and the MQTT protocol, a signal indicating that the test device has been turned on, that is, has accessed the corresponding test interface, and then test whether the interface is successfully accessed at this time according to the test instruction and send the detection result to the test machine. If the interface is not accessed, it is recorded as an interface access function damage; if the interface is successfully accessed, it is recorded as an interface access function intact. In a case where the interface access detection result sent by the machine under test and received by the test machine is intact, the test machine sends an interface removal instruction. In a case where the test device closes the corresponding interface access port, that is, removes the interface, the machine under test detects whether the interface has been successfully removed and sends the interface removal detection result to the test machine. The access detection result and the interface removal detection result are collectively referred to as the test result of the set interface in this detection.

[0042] Figure 2 An implementation flowchart of the interface performance test method of the embodiment of the application is shown Figure 1.

[0043] With reference Figure 1 The interface performance test method provided by the embodiment of the present application is applied to a test device, and the method comprises the following steps: 201, receiving a connection instruction sent by a test machine, wherein the connection instruction carries an interface identifier of a set interface for this time of interface test; 202, accessing the set interface of the test machine according to the interface identifier; 203, sending a signal of access success to the test machine; 204, receiving a test instruction sent by the test machine, and testing the set interface of the test machine according to the interface identifier in response to the test instruction, and sending a test result to the test machine.

[0044] Specifically, the test device receives a connection instruction issued by the test machine through a TCP / IP protocol and an MQTT protocol, and then the test device turns on the interface of a test connection end connected with the interface to be tested according to the interface identifier of the interface for this time of test to access the corresponding test interface of the test machine in response to the connection instruction. After the corresponding interface is turned on, the test device sends an access success signal to the test machine through the TCP / IP protocol and the MQTT protocol, receives a test instruction issued by the test machine to test the interface for this time of test, and finally sends a test result of the interface for this time of test to the test machine through the TCP / IP protocol and the MQTT protocol.

[0045] In the embodiment of the present application, in the case where the interface identifier for this time of test indicates that the interface type of the set interface for this time of test is a DP interface or an HDMI interface, receiving a test instruction sent by the test machine, and testing the set interface of the test machine according to the interface identifier in response to the test instruction and sending a test result to the test machine, comprises: receiving a resolution identifier and a test signal corresponding to a plurality of resolution identifiers sent by the test machine in response to the test instruction; comparing the test signal with a corresponding original signal according to the resolution identifier to obtain a comparison result; obtaining a plurality of comparison results for a plurality of resolutions supported by the test machine; and sending the plurality of comparison results to the test machine, so that the test machine sends the plurality of comparison results and the resolution identifier corresponding to each comparison result as a test result to the test machine.

[0046] In this embodiment of the present application, in the case that the interface type of the set interface of the tested machine is a USB interface or a TYPE-C interface, the test instruction sent by the tester is received, and the set interface of the tested machine is tested according to the interface identifier in response to the test instruction, and the test result is sent to the tester, which comprises: receiving the interface access detection result obtained by the tested machine in response to the interface access detection instruction for detecting whether the set interface is successfully accessed; removing the set interface in response to the interface removal detection instruction; receiving the interface removal detection result of the set interface detected by the tested machine in response to the removal detection instruction, and sending the interface removal detection result to the tester; wherein the interface removal detection instruction is an instruction sent by the tester to the tested machine in the case that the access detection result is received and the access detection result shows that the set interface is successfully accessed; and the test result comprises the interface access detection result and the interface removal detection result.

[0047] Specifically, after the test equipment is connected to and turned on the access port corresponding to the set interface of this test according to the interface identifier carried by the access instruction issued by the tester, the tested machine can detect the set interface. For example, after the tested machine detects the access performance of the set interface and sends the access detection result to the tester through the TCP / IP protocol and the MQTT protocol, the test equipment receives the removal detection instruction issued by the tester through the TCP / IP protocol and the MQTT protocol, and responds to the removal detection instruction to turn off the access port connected to the set interface of this test to remove the set interface of the tested machine. After the test equipment determines that the corresponding interface is successfully removed, the test equipment sends a removal completion signal to the tested machine through the TCP / IP protocol and the MQTT protocol, so that the tested machine receives the removal signal and detects whether the set interface of this test is successfully removed according to the removal detection instruction and sends the result to the tester.

[0048] It should be pointed out here that the above description of the interface performance test method applied to the test equipment and the method applied to the tested machine shown in the embodiments of the present application is similar, and has the same beneficial effects as the above-mentioned method shown in the embodiments of the present application, and thus will not be described in detail. Figure 3 The method applied to the tested machine shown in the embodiments of the present application is similar, and has the same beneficial effects as the above-mentioned method shown in the embodiments of the present application, and thus will not be described in detail. Figure 3 The method shown in the embodiments of the present application is similar, and has the same beneficial effects as the above-mentioned method shown in the embodiments of the present application, and thus will not be described in detail.

[0049] Similarly, based on the above-mentioned interface performance test method, the present application also provides an interface performance test system, which comprises a test equipment and a tested machine. Figure 3As shown, the system 30 includes: a test machine 301, used to issue connection commands and test commands, and receive test results from the test device sent by the machine under test (DUT) to perform interface testing on the DUT's designated interface according to the test commands. The connection command includes the interface identifier of the designated interface for this test, and the test command carries the interface test requirements for this interface test; a test device 302, used to connect to the corresponding interface of the DUT according to the interface identifier of the designated interface; and to test the interface of the DUT based on the test commands from the test machine; and a DUT 303, used to receive the test results generated by the test device in detecting the designated interface, and send the test results to the test machine; wherein the test machine, the test device, and the DUT can be connected to the same preset communication line via a network.

[0050] Specifically, the test machine is used to issue commands and receive results. The test equipment and the machine under test are used to receive the corresponding commands issued by the test machine to complete the corresponding test actions and send the test results back to the test machine. In this way, when a user views the interface test results of a certain machine under test, they can easily view the test results of all interfaces of the machine under test through the test machine.

[0051] It should be noted that, Figure 4 The RJ-45 network interface between the test equipment and the device under test is only an example; in practical applications, other suitable interfaces can be used for connection and communication, such as J-tag. Furthermore, Figure 5 The interfaces (USB interface, TYPE-C interface, DP interface and HDMI interface) in the figure are only illustrative and may include these interfaces. In actual applications, there may be multiple interfaces, or some of these interface types may not be included. Similarly, other interface types not shown in the figure may also be included. This application does not limit the number or type of interfaces included.

[0052] In this embodiment of the invention, the testing equipment may include: a body having a network interface for connecting to a network, thereby enabling communication with the machine under test (DUT) and the testing machine via the network; an interface access mechanism, located within the body and connected to the interface of the DUT, for accessing different interfaces of the DUT; an interface detection mechanism, located within the body and connected to the interface access mechanism, for testing the interface of the DUT; and a main control chip, located within the body and connected to the network interface, the interface access mechanism, and the interface detection mechanism, for receiving instructions from the testing machine and sending instructions to the interface access mechanism and the interface detection mechanism.

[0053] In this embodiment of the invention, the interface access mechanism may include: a DP access port, a USB access port, a TYPE-C access port, and an HDMI access port for accessing the machine under test; a USB switching module for receiving instructions from the main control chip to freely switch multiple USB interfaces in the USB access port to access the machine under test; and a TYPE-C switching module for freely switching multiple TYPE-C interfaces in the TYPE-C access port to access the machine under test according to instructions from the main control chip.

[0054] In this embodiment of the invention, the interface testing mechanism may include a signal decoding module and a data detection module. The signal decoding module decodes the test signal and generates test data, while the data detection module compares the decoded test data with the corresponding original data and sends the comparison result to the testing machine.

[0055] Specifically, when the testing equipment performs performance testing on the USB or Type-C interface of the machine under test according to the testing instructions, refer to... ​ The main control chip (e.g., a microcontroller unit, or MCU) connects to an RJ-45 network interface to receive commands from the test machine. Furthermore, the main control chip also communicates with the USB port switching module and the TYPE-C port module via the I2C (Inter-Integrated Circuit) interface to allow the main control chip to transmit commands to the corresponding modules via IC2. It should be noted that the connection method between the main control chip and each module is not limited; any connection method that enables the communication described in this application is within the scope of protection of this application.

[0056] The USB port switching module and the TYPE-C port switching module are connected to the corresponding USB and TYPE-C access ports for receiving USB and TYPE-C signals, respectively. They receive instructions from the main control chip to freely switch between multiple USB or TYPE-C interfaces connected to the device under test (DUT) for testing different interfaces. This effectively avoids the conventional manual plugging and unplugging of different interfaces when testing different interfaces of the DUT, significantly improving the efficiency of interface performance testing.

[0057] Furthermore, to better provide the TYPE-C signal to the device under test (DUT), the test equipment may also include a PD module. The PD module is connected to the TYPE-C access port and the TYPE-C interface switching module, and is used to parse the TYPE-C signal and provide it to the DUT.

[0058] When the test device detects the performance of the DP interface or the HDMI interface of the machine under test according to the detection instruction, the test device further comprises an interface detection mechanism, which can obtain the test signals of different resolutions sent by the machine under test through the interface access mechanism, then compare the test signals with the corresponding original signals to generate comparison results, and finally send the multiple comparison results and the resolution identifiers corresponding to the comparison results as test results to the test machine through the TCP / IP protocol and the MQTT protocol. ​
